Description

[Detailed description of the invention] Conventionally, in a combine harvester, a tying device is attached to the rear of the threshing device, and a straw bundle conveying body consisting of a straw bundle conveying chain and a clamping guide rail is attached to the discharge side of the tying device. The clamping guide rail of the straw bundle conveyor was connected to the holding frame of the straw bundle conveyor chain by a U-shaped rod via a support frame and a spring.

However, since the U-shaped rod has to detour the movement path of the straw bundle, when the straw bundle is held and conveyed in an upright position, the U-shaped rod protrudes significantly outward from the machine, such as vertically or longitudinally relative to the straw bundle carrier. I had to let it happen.

Therefore, not only did the U-shaped rod get in the way, but when the machine tilted, the straw bundles collided with the U-shaped rod, causing transportation problems.

The present invention improves the above-mentioned drawbacks, and makes it possible to mount the support of the clamping rail of the straw bundle conveyor so that it does not become an obstacle to the straw bundle conveyance, and also so that the support member does not protrude significantly outside the machine. The present invention aims to provide a straw bundle conveying device for a combine harvester, which is equipped with a tying device at the rear of the threshing device, and comprises a conveying band and a clamping guide rail installed opposite to the tying device on the discharge side of the tying device. The straw bundle conveyor is arranged diagonally toward the mown field side, and the receiver receives the ear side of the straw bundle released by the discharge arm of the bundling device, and the straw bundle is rotated to the starting end of the straw bundle conveyor. In a combine harvester designed to carry over, the front part of the arm is attached to a cylinder that is built above the collecting part of the binding device and has a drive shaft for the nodule part inside, and the arm is connected to the culm collecting part of the binding device. A support that extends rearward through the upper side across the side discharge path and the ear side transport path of the straw bundle transport body, and that the intermediate part of the support frame of the clamping guide rail is fixed to the rear part thereof, and that the support frame can be extended to the support frame. It is characterized in that the clamping guide rail is elastically supported via a rod and a spring.

The embodiment shown in the drawings will be explained below.A
is a threshing device mounted on a machine base having a traveling device, in front of which a reaping device and a grain culm conveying device are provided, and behind the culm discharge port of the threshing device A, a straw removal chain 1a and a A straw removal conveying device 1 consisting of a guide rail 1b is provided.

B is a binding device provided at the rear of the threshing device A, and the underframe 2 fixed at the bottom thereof has a plurality of wheels 3, 3, which are attached to the rear of the threshing device A. Since it rests on the rail 5 of the attached support frame 4, it can be set at a desired position by moving it laterally and tightening the handle 6.

In addition, the binding device B includes a door 8, a stock head receiver 9, a bundle car 10 at the bottom of the culm collection part 7, as in the conventional one.
It has a knot 11 and a discharge arm 12 on its upper part.

A steeply inclined guide plate 13 is provided at the lower rear of the straw transporter 1, and the upper end approaches the lower rear end of the guide rail 1b, and the steeply inclined guide plate 13 faces rearward downward. The front end of the gently inclined guide plate 14 extending toward the direction is overlapped with the lower end surface of the steeply inclined guide plate 13, and a box-shaped frame 16 is located slightly toward the rear of the overlapped portion. A pair of star foils 15, 15 attached to a shaft 17 which is supported by and constantly rotates is facing, and the distance between the rotation locus of the star foils 15, 15 and the steeply inclined guide plate 13 is such that the waste straw is at the overlapped portion. The distance from the gently inclined guide plate 14 is so small that the straw is caught between the protrusions of the star foil and scraped into it.

Reference numeral 18 denotes a stay that protrudes from above the box-shaped frame 16 toward the stock side, and the bases of a pair of guide rods 19 and 20 made of leaf springs are fixed to the tips of the stays, The tip of the guide rod 19 is the door 8
The tip of the guide plate 20 on the stock side faces the part facing the tubercle 11.

Reference numeral 21 denotes a guide rod fixed to the upper surface of the box-shaped frame 16, which is approximately parallel to the steeply inclined guide plate 13. A strong guide spring 22 serving as a receiver fixed to the tip side of the box-shaped frame 16 It rises from the rear edge of the gently sloped guide plate 14 and reaches above the rear guide plate 23 which is connected to the slope, and the gently sloped guide plate 14 and the rear guide plate 23 are formed in an inverted U-shape.

Reference numeral 24 denotes a straw bundle conveying chain which is held together with a holding frame 24a on the underframe 2 of the bundling device B by a pair of left and right stays 25, 25, and a clamping guide rail 26a opposite to the upper surface of the straw bundle conveying chain is attached to a support frame 26b with a spring 27. The front end of the arm 28, which is held in a hanging state via a support rod 27a that can move forward and backward, and protrudes forward from the support frame 26b, is connected vertically to a cylinder 29 that houses the drive shaft of the knot 11. A spring rod 30 which is connected to be tiltable and whose one end is removably engaged with a stopper of the cylinder body 29 and which is wound around the cylinder body 29 is stronger than the spring 27 and has an end bent on the upper surface of the arm 28. The part is locked.

31 is pivotally supported by a rod supported via a link ball 33 so as to be able to move back and forth and freely turn the front part left and right, and a link 36 supported by a handle 34 and a fan-shaped plate 35 having an arcuate long hole and whose rotation is adjustable. Tight pulley 37
The input shaft 38 of the binding device B, which is driven by a V-belt 37b attached to the rod 37a, moves the rod 32 back and forth through gears 39, 40, a crank rod 41, and a swinging arm 42.
Step 1: Strike the base of the straw that is concentrated at the rear to align the stocks one by one.

Next, to explain the operation, the straw removal conveying device 1
The straw discharged from the rear of the steeply inclined guide plate 13
and the star foil 15, and with both the plant base and the tip lying on the front end of the gently inclined guide plate 14, the plant is directed towards the culm collection part 7 by the star foil 15. I get sucked into it.

At that time, the star foil 15 is attached to the gently inclined guide plate 14.
Since the straw is approached with a small gap, the stock base and the panicle side of the waste straw are raked in two places, and the patsuka 1
Since the raking trajectory of No. 0 wraps when viewed from the side, the packer 10 takes over the waste straw raked by the star foil 15 while lightly pressing it with guide rods 19 and 20, and rakes it into the culm collection part 7.

When the door 8 senses a predetermined amount of convergence pressure and engages the clutch once, the needle hooks the string, the knotter 11 is activated, and the discharge arm 12 moves the straw bundle backwards while removing the knots. The straw bundles are blocked on the ear side by the guide spring 22, and a guide rod 44 protruding diagonally downward from the knot guide 43 is located at the starting end of the straw bundle conveying chain 24 and the clamping guide rail 26a. Since it is guided, it is released diagonally to the mown area behind.

At this time, the clamping guide rail 26a is supported by an arm 28 connected to a cylindrical body 29 containing a drive shaft of the knot 11 located away above the straw removal passage of the culm collecting part 7 etc. of the bundling device B. Therefore, the straw bundles being transported are transported smoothly without colliding with the arms 28, which are the supporting members of the clamping guide rails 26a.

Note that the spring rod 30 is connected to the clamping guide rail 2.
The spring 27 that directly presses the arm 6a is stronger, and the front end of the arm 28 is pivoted to the upward U-shaped receiver 29a by a horizontal pin, so a large clamping pressure is applied like a large bundle. Then, the arm 28 rotates upward against the spring rod 30 to absorb the above-mentioned excessive clamping pressure, thereby allowing for smooth conveyance.

In addition, in the event that the straw bundle conveyor is clogged with straw bundles, lift the clamping guide rail 26a and rotate the arm 28 upward, or pull out the base of the spring rod 30 from the catch 29b and rotate the arm 28 upward. By moving the straw bundle, the stuck straw bundle can be removed very easily.

Note that 45 is a string basket.

As mentioned above, the present invention includes a tying device attached to the rear of the threshing device, and a straw bundle conveyor consisting of a conveyor band and a clamping guide rail attached to the tying device on the discharge side of the tying device, which is oriented diagonally toward the already cut field. In the combine harvester, which is arranged at The front part of the arm is attached to a cylindrical body that is built above the culm and has a drive shaft for the nodule part inside, and the arm is connected to the ear side discharge path from the bundling device and the ear side transport path of the straw bundle conveyor. The middle part of the support frame of the clamping guide rail is fixed to the rear part of the frame, and the clamping guide rail is elastically supported through a support rod and a spring that can move back and forth to the support frame. Therefore, there is no need to connect the supporting frame of the clamping rail to the holding frame of the adjacent straw bundle conveying chain using a U-shaped rod as in the past, and the straw bundles are carried over from the bundling device and are conveyed in a pinched manner by the straw bundle conveyor. The straw bundles do not collide with the arm, which is the support member of the clamping rail, and are not disturbed during transportation, and the straw bundles are neatly clamped and transported toward the mown field while preventing disturbances in the straw bundle transportation posture and resulting clogging. can be released to

Furthermore, since the arm supporting the clamping guide rail is attached to the cylindrical body of the bundling device, the arm, which serves as a support member for the clamping guide rail, protrudes significantly backwards or vertically from the straw bundle conveyor like a conventional U-shaped rod. Therefore, the machine body can be made smaller and can be easily moved or stored, and it does not get in the way during maintenance and inspection of the rear part of the straw bundle carrier.

Further, the arm serves as a support member for positioning the clamping guide rail with respect to the straw bundle conveying chain and holding the clamping guide rail in the machine body, and the conventional clamping guide rail is used to hold the straw bundle conveying chain through the U-shaped rod. To enable a support device of a straw bundle conveying device to have a simpler structure than one in which the holding frame is connected to a frame and held in this state to the body via a support member, and to reduce the weight and cost of the body. I can do it.
